This invention relates to nozzles for liquid conduits and more particularly to an improved nozzle for use with lines of hose used for supplying gasoline and other liquid fuel t-o motor vehicles and the like but which is equally applicable to hose or other conduits used for a variety of purposes. Gasoline hose as heretofore used in filling the tanks of motor vehicles, particularly, have included a number of disadvantages due to the spilling of gasoline upon the vehicle during emplacement or removal of the hose nozzle at the filling aperture of the tank, these disadvantages including not only waste of fuel, but also damage to the paint ofthe vehicle, yas well as constituting a fire hazard. The disadvantages mentioned have existed notwithstanding the useof supplementary valves or other flow controlling media. 'Y

The ,primary object of the present' invention is to enable a hose nozzle to act automatically to start the flow Aof liquid through the'hose only after they end of'the nozzle has entered the lling opening of the tank or othervessel, and which will act automatically to shut off the flow prior to withdrawal of the nozzle.

Another object is to equip the nozzle with a valve adapted to be opened by pressure upon the nozzle in the direction of insertion into the filling opening, by cooperative frictional engagement of the valve supporting or carrying portion of the nozzle with the side walls of the lling aperture.

Still anotherobject is Vto enable the hose and valve to be retained in operative-position during use of the nozzle in the act of supplying liquid to the tank, the Vretaining means for the valve being releasable before release of the retaining means for the nozzle.

Yet other objects are to simplify and improve the construction of lling'nozzles generally and render the same more eiiicient for their practical purposes While also enabling the same to be manufactured at low cost.

Other objects and advantages of the invention will be hereinafter specifically pointed out, or will become apparent, as the specification proceeds.

With the above indicated objects in View,

the invention resides in certain novel constructions and combinations andy arrangement of parts, clearly'described in the following specilication and fully illustrated in the accompanying drawing, which latter shows embodiments of the invention as at present preferred. f

- In the drawing:

Fig. 1 is a side elevation of the presentnozzle construction; 1

Fig. 2 is a partial vertical section through the discharge end of the nozzle showing the parts in the position assumed preliminary to opening the valve;

' Fig. 3 is a bottom plan View of the discharge end of the nozzle; and

Fig. 4 is a transverse sectional view taken substantially `on the line 4 4 of Fig. 2.

The nozzle construction in this instance consists of a tubular body 10 which is desirably curved toi facilitate its insertion in the 7 usual filling opening 11 of a tank or the like, which latter may be the conventional gaso-V line tank 12 of a motor vehicle. One end of the nozzle 10 is provided with a suitable coupling 13 for attachment to a hose or pipe line. The discharge end of the nozzle body is equipped with automatically operating valve means to control the passage of liquid therethrough. Said means includes a tubular nosepiece l5 surrounding the discharge endv of the nozzle body, the lower end of the nosepiece having an inwardly extending wall portion 1G, providing a chamber 17 beneath the lower end 418of the nozzle body 10, the end of the inwardly extending portion 16 being arranged to overlap the inner side of this lower end 18. Y

Y To join the nosepiece 15 to the nozzle body l0, the inwardly extending portion 16 is provided with a transverse web portion 19 havf on the endpiece 23, the stem 20 being of such length as to allow slight relative movement between the nosepiece and nozzle body, such movement being limited in valve closing direction by the valve, and in valve opening direction by the web portion 19, the endpiece 23 acting as a stop in both directions of movement.

Means are provided to normally hold the valve to its seat 22, and for this purpose I provide, in this instance, resilient means in the form of a coiled spring 25 positioned in the chamber 17, this spring being effective between the lower end 18 of the nozzle body and the lower end of the chamber 17.

To enable the valve 21 to be opened only after the discharge end of the nozzle has been inserted within the tank 12, the nosepiece 15 is here constructed to cooperate with the filling aperture 11 of the tank so that the nosepiece will be limited as to the distance of its entrance within the tank, the nozzle body 10 being permitted an additional movement, relative to the nosepiece, sufficient to move the valve from its seat. Said means preferably include devices whereby a frictional engagement may take place between the collar 26 of the filling opening 11 and the nosepiece 15. Such frictional devices are here shown as a plurality of spring fingers 27, each of which may desirably be provided with a corrugated portion 28. The lower ends of the lingers 27 are secured to the outer side of the nosepiece as indicated at 29; and the upper ends 30 of the spring ngers extend outwardly and are free and bear against the underside of an annular flange 31 which is formed integrally with and substantially at a right angle to the nosepiece 15.

As the nozzle is inserted in the filling opening 11, the spring ngers 27 bear against the sides of the collar 26, the corrugated portions 28 of the spring fingers serving to increase the frictional effect. The nosepiece flange 31 acts as a stop to limit the entrance of the nosepiece into the tank and also as a shield over the opening 11 to prevent splashing of liquid from within the tank.

Continued movement of the nozzle into the tank causes the end 18 of the nozzle body to compress the spring 25, thus moving the endpiece 23 away from the valve 21 and permitting liquid to flow past the valve, through the passage 24, to the discharge end 14.

Suitable means are provided to hold the nosepiece and nozzle body in the relative positions ust described, during the filling operation. In this instance I provide detent devices, here shown as a pair of lugs 32 provided upon the to of the fiange 31, these lugs 32 being adapte to latch over spring fingers 33 provided at opposite sides of the nozzle body 10.

The frietional engagement between the spring fingers 27 and filling opening collar 26 is greater than that aorded by the detent members 32 and 33, so that when the nozzle is withdrawn from the tank the detent means will be first released so that the nozzle body will move relatively to the nosepiece, thereby effecting closure of the valve 21 and stopping the flow of liquid before the nozzle is completely withdrawn from the tank.

The valve 21 may be of any suitable construction, spherical, conical, semi-spherical, dished, fiat or otherwise, an essential feature however being the provision of a full and free opening to permit ready flow of the liquid past the valve.

Considerable particularities of description, as to materials, part details, dimensions, capacities and utilities may have been herein indulged in, but it will be understood that these statements, made with particular reference to that one, and the one now preferred, of the many possible embodiments of the invention which is illustrated in the drawing, are not in any way to be taken as definitive or limitative of the invention. Inasmuch as many changes could be made in the above constructions, and many apparently widely different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language contained in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said s to fall therebetween.
